Smart cards — also called chip cards or EMV cards — carry an embedded microchip that authenticates the card itself, not the cardholder's identity. Some implementations add a PIN requirement on top for extra assurance.
Strengths and limitations
They're genuinely good at preventing counterfeit cards when implemented properly, and they still function as a standard card when a reader isn't available. The catch is exactly that fallback: without a reader, many merchants just process the card as a regular one, which quietly erases the fraud-prevention benefit the chip was supposed to add. Reader adoption has historically lagged in some channels, even as chip cards themselves became standard.
What implementation requires
- Processor support for chip card services
- Card readers actually available where the consumer transacts
- A defined process for handling non-reader transactions
- A policy for whether a stolen card should still be able to use a reader
Approve orders when chip verification succeeds; reject when it fails. Non-reader transactions still need the rest of your standard fraud checks, since the chip's protection simply isn't in play.
